Abstract: PURPOSE: To quickly and effectively back up and restore a data base. CONSTITUTION: A CPU and a memory are connected together via a common bus in a data base backup system. This system includes a CPU 1 which performs the main control processing of the system, an operation RAM 5 which stores the data base to which the CPU 1 refers, and one or two or more backup RAMs 6. The RAMs 5 and 6 are put in the same address space of the system, and a backup write operations are applied to the RAMs 6 at the same time when the data are written in the RAM 5 from the CPI 1. Furthermore, a default ROM 4 is added to store a data base, together with a control part 20 which transfers the data in blocks among the memories 4 to 6 and a selector part 30 which switches the CPU 1. The ROM 4 and RAMs 5 and 6 are put in the same address space of the system, and the default expansion of data is applied to the RAMs 5 and 6 at the same time when the data are read out of the ROM 4.

Title: Absolute encoder
Inventor: HAYASHI YOSHINORI
IPC: G01D5/245
Filed: 1989-02-21
Abstract: PURPOSE:To obtain absolute position data without necessity of generating an origin signal nor counting the number of pitches by extracting a signal based upon variation in magnetism and a signal based upon waving from one track. CONSTITUTION:A ferromagnetic body is stuck on the outer peripheral surface of a measurement disk 11 and a pitch signal track Tr is formed on the outer peripheral surface by magnetization. On this track Tr, N and S poles are recorded alternately at constant pitch so that the intensity of the magnetism varies in a sine wave shape and its recording track waves in a sine wave shape. Further, the track is so recorded that the pitch of the recording by the magnetization and the pitch of the waving are repetitive numbers having no common prime number from the start point to the end point. Signal separating circuits 20 - 22 extract the signal based upon the repetition of the N and S poles and the signal based upon the waving from the detection outputs of magnetic senors 12 - 14 being arranged in opposition to the track Tr, and angle calculation parts 28 and 29 detect the absolute positions of the sensors 12 - 14 to the track Tr from the combination of both the signals.

Title: Reclaimer-condenser
Inventor: IMURA KOJI
IPC: F25B39/04
Filed: 1990-02-23
Abstract: PURPOSE:To improve capacity by unifying functions of a reclaimer and a condenser by a method wherein a receiving tray is provided for collecting high temperature steam which is made to flow for heating inside of an inner heat transmitting pipe after condensation together with condensed refrigerant, and cooling liquid is made to flow outside of an outer heat transmitting pipe to remove heat of condensation. CONSTITUTION:A cylindrical holder 4 is mounted on the upper end of an inner heat transmitting pipe 1. As the gap between the holder 4 and the pipe 1 is narrow, a dilute solution 21 can be sulfurized in film on the outer surface of the pipe 1. Thus refrigerant vaporizes easily from the dilute solution 21, and the solution can be condensed effectively. Further the lower end of the pipe 1 is shaped in U-letter so that the refrigerant accumulates in a V-shaped pipe 9. In this constitution, as high temperature steam sent inside of the pipe 1 cannot be blown out into the space between the inner heat transmitting pipe 1 and an outer heat transmitting tube 2, a reclaimer 1 and a condenser 2 can operate normally. In addition, by a double-pipe construction, in which an inner heat transmitting pipe works as a reclaimer and an outer heat transmitting pipe as a condenser, the velocity of the refrigerant steam is extremely low, and loss of pressure is very small. Thus the functions of a reclaimer and a condenser are very good.

Filed: 1994-03-11
Abstract: PURPOSE: To obtain more precise coarse adjustment for a telecommunications system during operation. CONSTITUTION: A telecommunications system which includes one main station that uses a TDMA frame structure and plural substations, e.g. PON-FITL systems are provided. These systems include means for coarse adjustment and small adjustment and obtain a coarse adjustment means based on a pseudo-noise sequence that is improved.

Abstract: PROBLEM TO BE SOLVED: To enhance printing quality due to a printer engine for binary output and to increase a processing speed. SOLUTION: In a printer controller (printer control device) 20, the image data sent from a host computer 1 is imagewise developed as multivalue data in a printable manner in a printer engine 10 and the imagewise developed multivalue image data is temporarily stored in an RAM 6 and the operation of a video DMA is started by a DMA controller 7.

Title: Surface treatment of spring
Inventor: ISHIDA MASAAKI
IPC: C21D7/06
Filed: 1999-02-19
Abstract: PROBLEM TO BE SOLVED: To improve the fatigue fracture resistance of a spring by projecting hard metal particles, having hardness not lower than a specific Hv value and equal to or lower than the outermost-layer hardness of a spring, onto the surface of a spring having a nitrided surface layer while controlling collision speed so that the instantaneous temperature-elevation limit of iron matrix becomes a temperature at which strain aging and work hardening take place and which is lower than a value at which softening by recovery recrystallization takes place. SOLUTION: Hard metal particles of 20-100 μm particle size, having 7.5-9.0 specific gravity and a hardness not lower than Hv 600 and equal to or higher than the outermost-layer hardness of a spring, are projected onto the surface of a nitrided spring at (70 to 200)m/sec collision speed. The collision speed is controlled so that the instantaneous temperature-elevation limit of iron matrix becomes a temperature at which strain aging by nitrogen atoms and work hardening take place and which is lower than a value at which the softening of the surface layer of the spring due to recovery recrystallization takes place. By this procedure, the surface layer is provided with high compressive residual stress, and microcracking can be prevented.  By holding, after the projection, at 150-250 deg.C for several minutes to 1 hr, the immobilization of the dislocation of the projection-affected layer can be secured, by which the spring with excellent durability can be obtained.
